-* Elan eKTF2127 I2C touchscreen controller
-
-Required properties:
- - compatible : "elan,ektf2127" or "elan,ektf2132"
- - reg : I2C slave address of the chip (0x40)
- - interrupts : interrupt specification for the ektf2127 interrupt
- - power-gpios : GPIO specification for the pin connected to the
- ektf2127's wake input. This needs to be driven high
- to take ektf2127 out of its low power state
-
-For additional optional properties see: touchscreen.txt
-
-Example:
-
-i2c@00000000 {
- ektf2127: touchscreen@15 {
- compatible = "elan,ektf2127";
- reg = <0x15>;
- interrupt-parent = <&pio>;
- interrupts = <6 11 IRQ_TYPE_EDGE_FALLING>
- power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>;
- touchscreen-inverted-x;
- touchscreen-swapped-x-y;
- };
-};
